I posted this one here last year. It just recently got repotted, and then went absolutely nuts, throwing out 4 new leaves, and a whole buncha buds. I think it has a total of 19 blooms.
And no, they don't open any more than that. They have little slits on the side which pollinating insects can enter. It's in a 4" pot.
